Can't comment on that processed fish matter but mosquitos there are beyond ridiculous in the summer (Finland ain't much better). Having dozens of bites on every bit of skin that isn't completely covered, constantly. One hitchhiker who I've met who had his one hitching hand uncovered counted 168 bites, on one hand, within 2 hours. When you hike, you have easily 100 of them sitting on you, your backpack, everything. They are also huge compared to central Europe.

Sure, you get used to being full of red spots, you stop scratching them, but occasionally you run some part of your skin against something and all hell breaks loose.

Then you come back to sanity and realize freedom has many shapes, and being able to dress as you like in summer is definitely one of them.
